The inobudirira kushanda nguva Fund

Kunanga unoshanda anoshanda nguva Fund - ukoshi ichi rinowanikwa nenzira yemaitiro yezviri uye pusa basa panguva pakuvhiya kwakawanda panguva chirimwa. Mune mamwe manzwi, zviri chakarongwa nokuda Workflow rinoreva zvikurukuru vatora karenda nguva, kureva mwedzi, kota kana gore. Tarisira kuti kwete chete kuisa inodiwa nhamba yevashandi, asiwo kuona chikuru zviratidzi wokushandiswa basa zvinhu imwe kambani. Kuita zviumbu H / h (murume-maawa), uye H / D (mazuva).

Kuti aone mari iyi sezvo pagore nokushanda nguva Fund zvakafanira kuisa nekarenda wemari. Mazuva kure pagore kana inosanganisira zvebhizimisi muoti, zvinoderedza kwakakura pakarenda nguva, uye mugumisiro ihurumende-nyaya (normative kana chezita) kukosha uchishandisa nguva. Asi zvichiguma kukosha haigoni zvizere kushandiswa kuita zvose basa kushandiswa. Asi chinhu chakadai anobudirira pavane kushanda nguva apo kwakakura mureza-nyaya nguva kubvisa zvirwere zvose, pazororo uye zvichingodaro. Kuti kuona aizviti kukosha kushanda nguva imwe mushandi anoda pakarenda nguva yakakwana kuti abvise zvitadzo zvose mazororo uye maawa uye mazuva. The Zvichaguma nguva chokupika basa mabasa hwakagadzwa nzira.

Fund yokushanda nguva, rakapfupikiswa kuna TRV achinzi kwakarongwa akatsunga kwakavakirwa Kunyanya pakuenzanisa nguva yakapiwa basa, dzinomiririrwa nokutevedzera mutoo:

TEV PS = X (Tc-Tprz -So-Tu-Tu-Tpr-TB TB - Tr) - (T + Tc + TCM) (vanhu / awa)

- TK - pakarenda pamazuva egore;

- TV - pakupera kwevhiki yegore;

- Tprz - zviri dzemazororo pagore;

- Kuti - iri misi uye mamwe anosiya (mazuva);

- TB - mazuva asipo kubva kumabasa (chirwere, mitemo uye zvichingodaro);

- Tu - kudzidza ngavabude;

- T, - nguva yakawandisa aurayiwe paruzhinji uye ehurumende mabasa (ukoshi pakutsvaga imwe zvebhizimisi statistically);

- TPA - kutadza ichi kuonekwa, achibvumirwa mutemo;

- PSM - ndiko kureba basa kusuduruka;

- TCM - zvinoderedza kushanda mazuva ekukurerai;

- T - a zvinoderedza kushanda mazuva kuyaruka;

- T - ndiye rutapudzo mazuva kushanda yezororo.

Nhamba Tu, TB, Tpr, Tr, TPK, TN - Mazuva kure nokuda kwechikonzero chakanaka - vari zvachose kunorondedzerwa basa mutemo maererano avhareji Data kuti rapfuura gore.

Background:

Sezvinoratidzwa kwenguva refu rokuzvidavirira tsika, anenge gumi muzana exponential kugadzirwa nguva vanoumba duku varasikirwa. Naizvozvo, kuti aite ine kukarukureta yokuchinjira kwazviri kuti kunodiwa kushandisa coefficient 0,88. Yeuka kuti 0,88 reshiyo - aumbwa randomly mumunda engineering kugadzirwa. Naizvozvo, nokuti zvebhizimisi, mufananidzo uyu angava yakasiyana.
